AUTOMOBILE-JACK.

Specification of Letters Patent.

Patented Oct. 22, 1912.

Application filed March 30, 1912. Serial at. 687,382.

T 0 all whom it may concern:

Be it known that I, HERBERT W. SEELY, a citizen of the United States,residing at Seligman, in the county of Yavapai and State of Arizona,have invented new and useful Improvements in Automobile-Jacks, of whichthe following is a specification.

This invention relates to an automobile jack designed especially for usein garages, whereby an automobile which is being stored for any materialperiod may be lifted and held out of contact with the floor, to relievethe tires from strain or to permit repairs and other operations to bereadily and conveniently performed.

The main object of the invention is to provide a simple, inexpensive andeffective device of this character by which the auto mobile may beeasily lifted and firmly supported, and as easily and convenientlylowered to the ground, the construction being such that the apparatusmay be readily operated by one man and without material expenditure oftime and labor.

The invention consists of the features of construction, combination andarrangement of parts, hereinafter fully described and claimed, referencebeing bad to the accompanying drawings, in which Figure 1 is a sideelevation of the jack,

- showing the position of the parts and adjacent wheels of theautomobile in position for raising the automobile. Fig. 2 is a similarview showing the automobile raised clear of the floor. Fig. 3 is a topplan view of the jack, with parts broken away to better show theconstruction. Fig. 4: is a vertical transverse section on the line M ofFig. 1. Fig.

5 is a detail perspective view showing the construction of the retainingrack and detent. Fig. 6 is a'similar view showing the construction ofthe fulcrum rack, lever and mode of applying the latter to the draftbars.

Referring to the drawings, 1 designates a base frame, adapted to restupon the floor of the garage or storage house, and comprising a pair ofparallel longitudinal bars 2 connected by cross pieces 3 and 4. Securedto the bars 2 adjacent their opposite ends are.

opposite pairs of wedge-shaped lower track blocks 5, having their upperfaces sloping upwardly and forwardly, as shown. These blocks'arepreferably made of wood and have their upper faces provided withmetallic wear plates 6. Secured to one of the by cross bars 14: and 15.

bars 2 immediately inrear of the forward block 5 is a plate 7 providedwith a series of ratchet teeth 8, constituting one element of a locKingdevice, as hereinafter described. Also secured to the front cross railat of the base frame is a metallic bar 9 having teeth or notches 10adapted to be engaged by the lower end of a draft lever 11. v I

Arranged above the base frame 1 is a similarly constructed supportingframe 12 comprising a pair of side bars 13 connected Secured to saidside bars 13 adjacent their ends are depending pairs of wedge-shapedupper track blocks 16 disposed above the companion blocks 5 and havingtheir faces sloping or inclined in the opposite direction thereto. Fixedto each bar 13 on the opposite sides of the block 16 are metallicretaining plates 17, which have their upper edges projecting above thebar and their lower edges projectplacement by the depending lower edgesof its weight against any tendency to roll off the jack. Preferably theblocks 5 and 16 are provided with dowel pins 5" and 16 to engage dowelseats 5 and 16- in the bars 1 and 12 whereby said blocks are madeadjustable on the bars with relation to the front blocks 5 and 16 forsupporting vehicles of different length.

' In practice, the automobile to be elevated is run into the spacesbetween the bars of the frame and the wedge-blocks 20 inserted under theaxles thereof, after which the frame 12 is moved forwardly, so that theblocks 16 will travel up on theblocks 5,

whereby-the automobile will be elevated, the rollers 19 reducing thefriction of motion' '14 of the frame 12 and project rearwardly indivergent relation therefrom and are secured at their rear ends to theside bars 13.1 The lever 11' is accordingly adapted for detachablepivotal engagement with a stirrup formed by the parts 2 l-and 25 and maybe successively engaged with the teeth or notches 10 and rocked toimpart an intermittent forward motion to the frame 12 until theautomobile has been elevated to the limit afforded by the track blocks.

Secured to one of the bars 13 and the adj acent forward block 16 is ahinge bracket 27 to which is hin ed or pivoted a locking dog or detent28 which is adapted to engage the ratchet teeth 8 of the locking bar 7.It will thus be understood that the lever 11 may be engaged with thefirst bar or notch 10 to pull the frame 12 forward a certain distance,in which it will be locked by the detent 28, the lever then adjustedinto engagement with the second notch or tooth 10 and operated to drawthe'frame 12 forward a greater distance, and so on until the fullforward travel of said frame is obtained, by which the automobile iselevated clear of the floor, the detent 28 successively interlockingwith the teeth 8 to hold said frame 12 from back ward movement. Theautomobile may be quickly and conveniently elevated in this manner sothat its tires will be lifted off the floor and the weight of themachine transferred from the tires to the jack, thus preventing thedamage occurring to the tires of an automobile which is left standingfor any considerable period. When the machine is so elevated convenientaccess may also be obtained to the frame thereof and parts carriedthereby for convenience in cleaning, oiling or making repairs. When itis desired to lower the automobile, the lever 11 is detached and thedetent 28 released and held elevated, whereupon the frame 12 will travelby gravity under the Weight of the machine down the inclined surfaces ofthe blocks 5 until the wheels can rest upon the ground surface. detent28, a chain or other pull connection 29 may be employed and extended toany suitable point for operation From the foregoing description, takenin connection with the drawings, the construction and mode of use of myimproved automobile jack will be readily understood, and

For convenience in retracting the it will be seen that it provides adevice of the stated character which is inexpensive of production andeflicient in use, and which may be employed with advantage to save wearand tear upon the tires and wheels when the machine is stored, as wellas to enable the machine to be elevated for the mechanism, means formoving the top frame forward intermittently, means for locking said topframe in each of its forward positions of movement, and means forrendering said locking means inoperative.

An automobile jack comprisi-nga base frame provided with a rack plate,an endwisemovable top frame, engaging inclined track surfaces betweenthe said frames, a stirrup carried by the top frame, a lever adapted fordetachable engagement with the rack plate and stirrup for moving the.top frame intermittently forward, looking mechanism for securing thetop frame in each of its positions of adjustment, and means forrendering said locking means inoperative? 3.
